Zero Plus Anything Is a World Poem by Jane Hirshfield

Four less one is three.

Three less two is one.

One less three
is what, is who,
remains.

The first cell that learned to divide
learned to subtract.

Recipe:
add salt to hunger.

Recipe:
add time to trees.

Zero plus anything
is a world.

This one
and no other,
unhidden,
by each breath changed.

Recipe:
add death to life.

Recipe:
love without swerve what this will bring.

Sister, father, mother, husband, daughter.

Like a cello
forgiving one note as it goes,
then another.
